Q: What is the primary charge carrier in n-type semiconductors?
Solution: In n-type semiconductors, electrons are the majority charge carriers due to the addition of donor impurities.
Steps: 5
Step 1: Understand what a semiconductor is. A semiconductor is a material that can conduct electricity under certain conditions.
Step 2: Learn about n-type semiconductors. N-type semiconductors are created by adding impurities to a pure semiconductor material.
Step 3: Identify the role of donor impurities. Donor impurities are elements added to the semiconductor that provide extra electrons.
Step 4: Recognize that these extra electrons become the majority charge carriers. In n-type semiconductors, the added electrons outnumber the holes (missing electrons).
Step 5: Conclude that in n-type semiconductors, electrons are the primary charge carriers because they are the most abundant.
